expand (sin(x)+3)(sin(x)-4)

expand

(sin (x) + 3) (sin (x) - 4)

sin^{2} (x) - sin (x) - 12

Solution steps

(sin (x) + 3) (sin (x) - 4)

Apply FOIL method

(sin (x) + 3) (sin (x) - 4) : sin^{2} (x) - sin (x) - 12

= sin^{2} (x) - sin (x) - 12

2 (4 - π)

\frac{6 ( 4 x ^{6} - 6 x ^{3} + 4 x ^{2} - 5 x + 6 )}{( 3 x - 1 )}

(x - 4) (x - \frac{5}{2})

(2 + y) (y - y^{2})

u (u - 4)
